"WRAPPING-MACHINE.

To aZZ whom it may concern: I

Be it known that I, E1111. JAGENBERG, a

subject of the German Emperor, and resi dent of 107 l-limmelgeisterstrasse, Dusseldorf, Germany, manufacturer, have invented certain new and useful Improvements in and Relating to lVrapping-Machines, of which the following is a statement.

The present invention relates to a wrapping device for wrapping machines, which serves for partly wrapping and simultaneously sharply folding the wrapping sheets for rectangular packages, boxes, vessels and the like.

The subject of the present invention is ere a pawl feed gear 3 intermittently from a cam on shaft 4. The first package is taken from this belt 2 by means of grippers 5 and moved into the wrapping position. The arms 6 of the grippers 5 are pivotally fitted to the slides 7 which are reciprocated by aid of levers 8 from a cam on the shaft 4, and are slidably fitted in sleeves 9, which are hinged to levers l0. ;Tl18S6 levers are fitted to vertical shafts 11 which are rocked by cams fitted to shaft W hen the levers are rocked inwardly, the grippers close, and vice versa. When the packet has been advanced by the grippers, the web of paper 25, which unwinds from the roll 26 is drawn forward by means of tongs 22, which are fitted to a slide 23, reciprocated by means of a lever 24 from a cam fitted on shaft 4. The roller 27 applies adhesive to the respective parts of said paper. The web of paper .thus lies beneath the package. Now two rods 13 slidably fitted in the bedy of the machine are lifted by means of hell crank 12. To these rods 13 are secured two plates 14. The lever 12 carries a roller 15 hich engages in a cam disk 1'? fitted At the same time a plate 18 is it above onto the package, the said p being fitted to a'rod 19 slidably fitted in body of the machine, which is operated by means of a lever 20, a rod 21 and a cam. i The package isthus, at top and'bottoni iuifilOSGii Patented May 18, 1915.

between the plates, which now are simultaneously lowered, and thereby force the package between the folding walls 28, 28. While the package is thus forced down, the knives 29 will have cut off the wrapping sheet of the required length, by the lower knife, which is fitted to a rod 30 being forced upwardby a cam 31, and the tongs 22 have opened in consequence df a small advance of the slide 23 to the left, (Fig.1), as the upper arms of the tongs have been lifted by means of a rod 32 moving in aclamp. The ends of the wrapping sheet are thus free and are now turned upward by the walls 28, 23 (Fig. 4). To the folding walls are fitted bolts 33, 33, which are displaceably fitted in brackets 34. The. bolts 33 can be fixed in position by means of screws 35, and the bolts 33 are forced forward by springs, but may be withdrawn by a crank 36. The wall 28 is so adjusted, that the package fits tightly between the folding Walls.

are successively advanced, which are hinged The vwrapping sheet is-thus smoothed down at i the sides. Th m. folding slides 37, 37

to levers 38, operatedby aid of rods 39 from cams on shaft 40. The inner ends of the to their face, narrower plates 45 are fitted on bolts 44 which plates 45 are likewise curved at top and bottom and fitted on their inner side with curved flat sprin s 46. Against the fiat springs bear rollers 4 and 48, which are fitted toarrns 49 and 50, respectively, which again are fitted to rods 51, arranged next to rods 41. The rods 41 and 51 are fitted into the same guides in the body of the machine, but are displaceable relatively to each other, as the upper ends of the rods 51 are loosely fitted in slots 52, formed by the plates 53 fitted to rods 41. The rods 51 are held in their lifted position by means'of bolts 54 fitted tothem and levers 55, fitted .to shaft 56, .which is turned by a lever 57, a rod 58.;3lltlf5fl cam on shaft 4.

By their gravity the plates 42 and as weight downward, so that their rods'bear with the plates 53 on the rods 51. When these rods 51 are lowered by the turning of levers 55, 57 therefore also the folding plates 42, 45 move down and press the parts of the tubular wrapped paper projecting at the sides beyond the package down on the top surface (Figs. 3, '6).v The folding walls are of the same length as the tubular wrapping, so that the plates as slide down along their inner sides. The result is that the paper Wrapping is smoothly folded down. "When, now, the plates 42, 4:5 bear down on the plates 53, or when the plates 53, which have shoulders 59, bear against elastically fitted bolts 60, the rods 51 will be thereupon further lowered alone, and the rollers 47, 4:8 fitted. to'them will glide downward on the flat springs 45, 46 and rock toward outside in consequence of the curved shape of the plates 42, 45, so that they are pressed against the package or the folding walls respectively. Thereby the wrapping sheet will be folded over sharply (Fig. 6). When the rods 52 move upward again, the rollers I7,

48 glide 0d the flat springs, so that the springs 61 can withdraw the folding plates, and then the upper ends of the rods 51 bear against the plates 53, so that also the rods 41 are lifted.

After the Wrapping has been folded on the upper side, the package is pushed by means of a slide 62 longitudinally from the space between the folding plates. The slide 62 is fitted to a carriage 63, which is reciprocated by means of two levers 6:1, 65 coupled together, of which levers the lever 65 engages with a roller in a cam "disk 66. The carriage 65 has a bevel 67 and on it rests the free arm of the bell crank 36, by

means of which the folding Wall 23 is Withdrawn. When thecarriage 63 laced, the bevel 67 forces the free arm 0 -e bell.

crank-36 upward, and the folding wall 28 rececle's, and by means of a lever 68, which is coupled by means of rod 71 with a lever 69,

the folding slide 37 is lifted. The package is thus lying loose between the folding Walls and may be easily removed by the slide 62.

ed to engage the wrapper at the end -0 a package, a pair of additional plates extending outwardly at right angles thereto and adapted to double portions of the wrapper protruding from said end, means for forcing the first named plate against the package, and additional means for forcing the last named plates against said doubled wrapperportions.
